MOUNTING OF DOLLY-WHEELS AND DASHERS.

Specification. of Letters Patent.

atentetl July 28, 1914;.

Application filed January 7, 1914. Serial No. 810,738.

To all whom it may concern Be it known that 1, JAMES L. Corrrnm, a citizen of the United. States, residing at Day+ ton, in the county of Montgomery and State of Ohio, have invented certain new and use fnl Improvements in Mountings of Dolly Wheels and Dashers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in the mounting of the dash ers or dolly-wheels of washing machines.

The object of the invention is to provide a mounting for such devices which is both simple and efficient and by means of which the parts, to-wit, the dolly-wheel, shaft and cooperating parts may be easily assembled and when assembled will not be liable to become disconnected through the operation of the machine, as will hereinafter more fully appear from the description to follow in connection with the accompanying drawings.

in the accompanying drawings, Figure 1 is a side elevation of a washing machine of the power type the same being equipped with my invention. A portion of the side of the tub is broken out to facilitate disclosure and the legs are removed from the tub. Fig. 2 is an enlarged vertical section approximately through the center of the dolly-wheel, part of which, as well as part of the lid of the tub, being broken away. Fig. 3 is a sectional view on the line aa of Fig. 2. Fig. 4t is a side elevation of the shaft of the dolly-wheel showing modified means for preventing the dolly wheel from moving to a position from which it might leave the shaft. And Fig. 5 is a sectional view through said shaft on the line 6-4) of Fig. 2.

In the description to follow and in the drawings, similar reference characters indicate corresponding parts.

Referring more particularly to said drawings, 1 designates the tub of a washing machine provided with a hinged lid 2. A hearing 3 provides a journal for a shaft 4: upon the upper end of which a pinion 5 is mounted. A rack 6 is geared to this pinion and is driven from a motor 7. Any driving means may be used to oscillate the shaft l, either power or manual. The said shaft 4: is rigidlysecured to an enlarged shaft 8 which is the shaft proper of the dolly-wheel or dasher 14. Upon this shaft 8 said wheel is slidably mounted. The dolly-wheel is of the usual type having the necessary number of clothes-agitating pins 15. The shaft 8 has four oppositely arranged longitudinal surface ribs 9 and 10 two of which, to-wit, t), extend to the upper end of said shaft and the other two, to-wit ribs 10, terminate below the upper end of said shaft. At the lower end of said shaft the ribs 9 and 10, respectively, are joined by two oppositely disposed lugs 11. These lugs 11 provide shoulders which prevent the dolly-wheel d ropping from the lower end of the shaft. The dolly-wheel is secured to a plate 13 which has an integral collar 12 forming the axial opening through which the shaft 8 extends. Inwardly projecting lugs 16 extend from opposite sides of the axial opening of the plate 13 and these lugs engaging the lugs 11 on the shaft 8 prevent the dolly-wheel from leaving the shaft although said wheel may be free to slide up and down upon said shaft. The ribs 10 terminate essentially a distance below the upper end of the shaft. 8 slightly greater than the depth of the dollywhecl collar '12 in order that the d0llywheel and shaft may be assembled. In assembling said parts the lugs 16 on the plate '13 are brought in alincment with the two spaces on the shaft 8 between the ribs 9 and 1.0 which are not closed by the lugs 11. The dolly'wbcel is then moved upwardly until the collar 12 is above the top of the ribs 10 and the said wheel is then turned or the shaft is turned until the lugs '16 enter the spaces between the ribs 9 and 10 which are crossed by the lugs 11. The dolly-wheel may then be permitted to drop until the lugs 16 and 11 engage. The bottom of the dollywhccl or lower side thereof is fitted with a cap 17 which incloscs the lower end of the shaft 8 and prevents the wheel from rising at any time to such an extent that would bring the collar 12 above the top of the ribs '10. As a consequence, the wheel is always maintained in positions with the lugs 16 between the ribs 9 and 10 and is consequently oscillated by the shaft 8 when power is transmitted to the shaft 4:. The use and purpose of the cap 17 is to prevent the clothes from coming in contact with the shaft 8 and any consequent liability to be Wound therearound. Should the cap 17 be dispensed' with any other suitable means might be employed to prevent the wheel from rising to a position which might bring the collar 12 above the ends of the lugs 10 and in which event the dolly-wheel would not oscillate. For example, such means might be in the nature of a pin projected from the shaft 8 a distance above one of the ribs 10 less than the depth of the collar, as shown in Fig. 4.

Having described my invention, I claim.

1. In a device of the type specified, the combination with a dolly-wheel having its axial opening provided with inwardly projeo'ting oppositely disposed lugs, of a shaft having a plurality of longitudinal ribs two of which terminate below the upper end of said shaft, and lugs extending between said ribs and closing the space between said ribs on two opposite sides of the shaft, said lugs being adapted to cooperate with the lugs and y the axial opening of the dolly-wheel and tire length of said enlarged portion and shorter and one of the longer ribs and comaintaining said dolly-wheel upon the shaft.

. 2. In a device of the character specified, the combination with the dasher having a l central opening with oppositely disposed inwardly projected lugs, of a shaft a portion of which is enlarged and provided with a series of longitudinal and uniformly separated ribs which engage said lugs to impart reversed oscillatory movement to said dasher, some of said ribs extending the enothers being of less length than said enlarged portion, and oppositely disposed shoulders on the lower end of said enlarged portion and extending between one of the operating with the lugs at the central openingof the dasher to maintain the dasher in an operative position.

In testimony whereof I afiiX my signature, in presence of two witnesses.
